 27 Apr 2008 21:01 Hspice error message please help |
|
|
|
Hi, I am trying to simulate the ADC i have designed using Hspice. I have a clock running at 20Mhz. i.e a period of 50 ns. I need the simulation to run till 100 milli seconds becuase i am using a current mirror ramp generator for generating a ramp vooltage which requires that much time for producing a ramp output as i am using a 1 uf capacitor for charging.
When i try to simulate in Hspice using .Tran 1n 1m ( i ran it for 1 milli sec with a step of 1 ns) ( i tried a step of 10ns also)
it takes 4-5 hours for simulation and then it stops with an error message saying
**error** error happens when writing waveform for POST=1
time: command terminated abnormally.
Is it because of the memory problem? Can anybody please help how to solve this issue?
Thanks,
RC.
